Hey Dawg...you in LUCK!!....having just converted a double fuel tank set-up to a single, I got a SS fuel filler and SS 90* fuel vent fitting left over...no, they ain't free, but I'll make a helluva deal, just cause it's you...
Here's what I installed on the 21...
And here's the ones I didn't install just sittin around gatherin dust
The set...
Can't think of a place I'd rather them be than that Purdy Lil 21 of yours, so I'll make a special price on both iffn you want 'em...
They came from West and are now $30 for the filler and $23 for the vent...you can have 'em both for $25 plus shippin...if you just want the vent, it's yours for 10 bucks plus shippin...one thing to tell you...the vent head is just a lil too small for the hole in the hull after the original was removed..I found a rubber grommet(seen in the pic above) that worked perfectly...
If you don't want either, you still my favorite Dawg...
